‘68 Dart, One tail light not working.

replaced bulb and still not getting a brake light or turn signal light on the driver rear..while removing a nest of speaker wires and radio wiring from an aftermath radio that was added in the past I did come across this little dude that was very warm to the touch when nothing was on..

Obviously local parts stores don’t even have a listing for such. Just the normal 2 terminal flasher, which it also has.. I don’t think this is my tail light issue but I don’t think it’s supposed to be hot like that at idle.. checked the harness plugs and sprayed contact cleaner on them.. still nothing. Another thing I need to replace is the turn signal switch. The little plastic cam I guess you call it broke and it doesn’t stay engaged when you turn on the right side blinker …
